For: memory operations -> stores
...
This is the first incremental patch to implement this feature. It adds no
functionality to LLVM but setup up the information needed from targets in
order to implement the optimization correctly. Each target needs to specify
the maximum number of store operations for conversion of the llvm.memset,
llvm.memcpy, and llvm.memmove intrinsics into a sequence of store operations.
The limit needs to be chosen at the threshold of performance for such an
optimization (generally smallish). The target also needs to specify whether
the target can support unaligned stores for multi-byte store operations.
This helps ensure the optimization doesn't generate code that will trap on
an alignment errors.
More patches to follow.

SelectionDAGLegalize::ExpandLegalUINT_TO_FP method.
Add a new method, PromoteLegalUINT_TO_FP, which allows targets to request
that UINT_TO_FP operations be promoted to a larger input type. This is
useful for targets that have some UINT_TO_FP or SINT_TO_FP operations but
not all of them (like X86).
The same should be done with SINT_TO_FP, but this patch does not do that
yet.

It is not safe to call LegalizeOp on something that has already been legalized.
Instead, just force another iteration of legalization.
This could affect all platforms but X86, as this codepath is dynamically
dead on X86 (ISD::MEMSET and friends are legal).
